EPAM Systems Senior Data Engineer interview questions

Online Coding Test: 1hr Technical Round 1: 1.5 Hr Technical Round 2: 1.5 Hr Managerial Round: 20 Min HR Round : Didnt Happen I endured a grueling virtual interview process for Pune location that involved a coding test and two in-depth technical rounds covering a wide range of topics including Python, SQL, Spark, Pyspark, AWS, Databricks, warehousing, and more. To my utter disbelief, after investing a total of 3.5 hours and clearing all these rounds, a manager dismissed me as 'technically unfit' following a superficial 20-minute discussion for unknown reasons. It's clear this company has no regard for candidates' time or effort. To be rejected so abruptly after such a rigorous evaluation is insulting. The HR representative expressed astonishment at the manager's decision, stating they were 'disappointed' and 'surprised' by the outcome. Unfortunately, they informed me that the manager's decision was final and couldn't be overruled. It’s unacceptable for a single individual to hold such power and make such reckless decisions. It seems you dont trust your own hiring process. I strongly advise anyone considering this company (particularly in India) to exercise extreme caution. Beyond the questionable interview process, this company has a infamous reputation for its hire-and-fire policies. Only proceed if you have exhausted all other options.
